Sign Language Glove

A gesture recognition glove built using flex sensors and Arduino. The system reads finger bending levels and converts hand gestures into simple readable outputs through serial monitoring.

The project evolved from a single-sensor prototype to a 4-finger sensing glove for improved gesture detection.

1. Arduino Uno
2. 4 × Flex Sensors
3. 4 × 10kΩ Resistors
4. Connecting Wires
5. Glove / Fabric base
6. Breadboard
7. USB Cable / Battery

Each flex sensor works as a voltage divider with a 10kΩ resistor.

Wiring (for each sensor)

1. One pin → 5V
2. Other pin → Analog pin + one side of 10kΩ resistor
3. Other side of resistor → GND

Pin Mapping (Final System)

1. Finger 1 → A0
2. Finger 2 → A1
3. Finger 3 → A2
4. Finger 4 → A3

At the beginning, only one flex sensor was used (A0) to understand how the sensor behaves and to calibrate threshold values.

This step helps you:

1. Observe raw analog readings
2. Decide bending thresholds
3. Verify basic gesture detection logic

Once the values were stable, the same setup was expanded into a full glove system. for testing only single sensor use this code flex_sensor.ino and for 4 sensor glove use flex_sensor_glove.ino files are attached below

Flex sensors change resistance when bent. The Arduino reads analog values and maps them to predefined gesture states.

The system first validates behavior using a single sensor, then expands to a full-hand gesture recognition system using four sensors.
